I do that all the time.
You just pull slow, just like you do with other pull gauges, but watch the numbers. Of course when it breaks it drops down but if you watching you can get the numbers dead on. Second pull you know where the break occurs and you can slow the pull at that point and hit it between the eyes.
Got an idea on doing another one with stuff I have around the garage that I think will be cool. Might post it when I get around to it.
I really like the way this thing turned out and how it works.
No one more surprised than me.

extremely inventive idea for a trigger pull gauge. well done.

here is an idea, or question. are you using a vice for the gun when using your gauge? if not, use a gun vice or similar to see if it makes it easier to use the gauge.

 

Nope. Lay the rifle on bi-pod with a couple of rice filled bags behind stock. 3 lb pull won't move a 7 lb gun. You can also put the barrel on something soft on the floor and the stock pointed up (works great and won't damage the crown). You have a heavy pull just put pressure on the stock. It also gives you a great view of the digital screen.
I had the stock off and just the barrel sitting on rice bags and the pull gauge never moved the rifle. If it does, just put your free hand on the barrel.
Easy peasy.

 

I have a lead sled solo that works great. I did test it on the Solo with the same results.
Like I said, I didn't think it would be that accurate.
It's easier if you have it in a vice or something to keep in place.
Easier to control the speed of the pull.
Your right.

i have a Wheeler trigger pull gauge that i bought many years ago. i just clamp the rifle or pistol in my bench vise when i testing trigger pull weights. i found i can get more consistent results that way, without wresting around with the gun.

 

That is pretty creative. Congrats!

I have never measured trigger pull or muzzle velocity on any of my guns. I have triggers, better triggers, and worse triggers, guns that I shoot poorly and guns I shoot worse. I am a minute of pie plate kind of shooter who doesn't get into the small details. But I still love it.
